Mich, a corporation of Michigan Application November 27, 1939, Serial No. 306,340

This invention relates to cash registers. It is particularly concerned with providing a printing mechanism for a key-operated cash register.

In key-operated cash registers it is desirable to have the keys operable with as light a pressure as possible and to have this pressure constant throughout the stroke of the keys. In my prior Patent No. 2,070,059, February 9, 1937, an indicating, nonprinting, key-operated cash register is provided in which the key load is exceptionally light and uniform. The present invention comprehends the addition of a printing mechanism to this machine without appreciably increasing the key load or disturbing its uniformity.

The general object of the invention is to provide an improved key-operated printing cash register having an easy and uniform key action.

Other objects and advantages of the invention will appear from the following specification and drawings.

The invention is shown applied to the Burroughs key-operated cash register disclosed in 'Pasinski No. 2,070,059, February 9, 1937. The

mechanism of this machine will be briefly de scribed, reference being made to said Pasinski patent for further details. It is to be understood, of course, that the invention can be applied to other types of cash registers 0r calculating machines.

The present application is a continuation of my prior copending application Serial No. 147,429, filed June 10, 1937. Figs. 19 to 22, inclusive, of the present drawings have been added to illustrate the invention more clearly, said figures being duplicates of those in another of my copending applications, Serial No, 147,431, flied June 10, 1937, of which this application is a continuation-in-part.

GENERAL CONSTRUCTION The operating parts 01 the machine are contained within a'housing H (Fig. 1) and are supported between right and left side plates, the left side plate i being shown in Fig. 2. The plates i are maintained in spaced relation by tubular cross members 2 and by other cross shafts on which the mechanism of the machine is mounted.

The machine is operated for item entering by two rows of depressible keys 4 on the ends of key levers 4 pivoted on the shaft 5. The keys may be depressed from the full to the dot-dash position of Fig. said levers being urged to their normal positions by springs "I. There are three denominations of keys, namely, cents, tens-oicents, and dollars with the usual number of keys in each denomination. Each key lever has a rearwardly and upwardly extending arm 3 positioned to engage a main operating shaft, or universal bail, ii carried by arms i2 fixed to shaft 6 near each end thereof. The shaft H with its supporting arms i2 constitutes a rockin bail which is urged clockwise by springs H (Fig. 3) secured to forwardly projecting portions I03 of the levers ii. The upper ends of the levers i2 terminate in full-stroke sectors 16 (Fig. 4) engageable by pawls, not shown, that insure a hill stroke being made at each key depression. A key coupler i8 is pivotally supported on the shait ii and spring urged clockwise. This coupler extends substantially across the machine and it is positioned so as to be engaged by projections IS on the key levers l of all denominations so that the keys may be partially depressed and latched to the key coupler, sometimes called presetting.

The upper end 9 oi each key lever has a differential cam slot 23 in it (Figs. 3 and 4), said slots being of different inclinations according to the value of the keys. A ball 30 (Fig. 2) is provided for each of the three denominations, said bail being of a length suflicient to be engaged by the cam slots 23 of the key levers or its denomination. Each bail is carried by spaced arms 31 journaled on a shaft 32. Each bail 30 is also connected to an indicator indexingyoke 33 (Fig. 7) by a forked arm 33. The yokes 33 are connected to indicator tab magazines 35 (Fig. 2) carrying indicator tabs 35 bearing indicia from 1 to 9. The yoke 33 for each denomination is thus differentially positioned in accordance with the key depressed and the indicating mechanism is correspondingly indexed. After the magazines 35 have been indexed, the indexed tabs are raised by appropriate mechanism 35 which has not been illustrated in detail, the same being fully described in my prior Patent No. 2,070,061.

A registering mechanism, or totalizer, is provided comprising a. plurality of register pinions 36 (Fig. This registering mechanism is of the type disclosed in my prior Patent No. 2,070,062, being also described in more detail in Horton 1,326,504. It is provided with a suitable tens-transfer mechanism and is operated as described in said Patent 2,070,062. This operating mechanism will be briefly described.-

The register pinions 36 are differentially actuated by the denominational bails 30. Since the parts operated by each of the three bails I. has a. link ll (Fig. '1) connected to an arm of its member 34. The forward end of the link Al is connected by another link 4| to an actuator rack 42 pivoted at 43, there being an actuator rack for each denomination. The actuator rack 42 is in constant mesh with a gear ll (Pig. 6) which carries a pawl [3 spring urged to a position to engage the lace of studs I on a gear 55. The gear BI is in mesh with a register pinion 33 (Fig. 6) that is fixed to the register indicator dial 33. The pawl II is mounted so that, when the gear I is rotated counterclockwise (Fig. 6), it will engage one oi the studs II and rotate the gear II, but, when the gear 43 is rotated clockwise, the pawl will merely pass over the studs II.

The arrangement is such that, when a selected item key of a denomination is depressed, the corare alike, only one will be described. The bail 7 responding ball 30 is moved forward, links ll and II are thrust forward, and the actuator rack 42 is rocked counterclockwise irom the position of Fig. 2 to that 01 Fig. 7 and to an extent corresponding to the value of the key depressed. This movement 01' the actuator rack rotates the gear 43 clockwise but this has no effect on rotating the registering mechanism. When the item key is released, the bail 3|, links H and associated parts are restored to normal by restoring bail 31 (Figs. 2 and 7) which is urged counterclockwise or to the right in Fig. 7 by springs not shown. During this restoring movement, the actuator rack 42 is rocked clockwise which causes the gear 43 to be rotated counterclockwise, and this movement is transmitted to the register pinion which is rotated an amount corresponding to the value of the key depressed. For iurther details of the operating mechanism or the register, reference is made to said prior Patent No. 2,070,062.

PRINTING The section of the machine by means of which printing is accomplished includes equipment tor handling paper as well as the printing mechanism proper. These parts are on the right-hand side of the machine and within the housing H as shown in Fig. l. The several mechanisms will be described separately under the headings (1) paper section; (2) indexing the type-carrying members; and (3) printing hammer operation.

1. Paper section Printing is performed on paper in the form of a continuous record strip P (Figs. 1, 4 and 21) extending from a supply roll 31 to a storage roll II (Figs. 4 and 21). The paper equipment is 0! the type in which, during each machine operation, the paper is moved from a position where the last entry is visible to a printing position where printing occurs, after which the paper is returned to a position where the currently printed entry is visible, line spacing occurring automotically.

Referring to Figs. 4 and 21, the paper strip P passes from the supply roll 01 under a shaft Ill, past the printing line of the printing mechanism later described, about a. stationary shaft 3|, over a stationary paper table 3!, and over a stationary guide il to the storage roll II. In the normal position of the parts, the last entry, such as the total 00010.55 in Fig. 1, is visible through a sight opening 203' in the cover 233. The spools on which the supply and storage rolls '1 and II are wound are carried by shafts l2 and I3, respectively, supported by a. pair of spaced bell crank levers H pivoted on a shaft 13, one of said bell cranks I4 being shown in Fig, 4 and both in Fig. 21. The paper strip is slid over the stationary guides and paper table to bring it to printing position by rocking the bell cranks I4 counterclockwise about shaft I8 from the position of Fig. 4. After printing occurs the bell cranks are rocked back to normal and the paper strip is returned to its former position except as it is automatically line spaced so that the currently printed entry will be the visible one. Automatic line spacing is accomplished by a pawl I5 (Fig. 4) which engages a ratchet wheel as the bell cranks 14 rock counterclockwise in Fig. 4. The

'parts are arranged so that pawl I5 causes the storage roll to be rotated a distance sufficient to move the paper strip one line space. During the return movement of the bell cranks 14, pawl I5 slides over the teeth of the ratchet wheel 15. The paper may also be line spaced manually at the option of the operator by means of a key 'I'I (Fig. 4) having a nose positioned to engage the teeth of the ratchet wheel 15.

The bell cranks I4 are rocked by means of an arm I8 (Figs. 4 and 21) pivoted on a shaft 88 carried by the side plates of the machine. This arm has a cam slot I8 engaging a roller 12 on the right-hand end of shaft 12. The rear end of the arm I8 has a cam slot 82 engaging a bail carried by two arms 84 pivoted on the shaft 6 and positioned in front of the universal bail II,

said arms and ball being urged clockwise in Fig. 4 by springs 88. When an amount key is depressed, the universal bail II is moved forward which rocks the arms 84 and ball 83 counterclockwise. This rocks the arm I8 clockwise to swing the bell cranks I4 counterclockwise, thereby moving the paper from visible to printing position.

When the amount key is released, the arms 84 are returned clockwise by their springs 86 to restore the parts to normal which includes rocking the bell cranks I4 to normal to thereby return the paper to visible position.

The supply and storage spools are also rocked to move the paper from visible to printing position and return by means of the total-taking lever 59. This lever is pivoted atv 68 (Fig. 4) and, when a total is to be taken, it is pulled forward by the handle 68 which rocks the lever about the pivot 88 in a counterclockwise direction. Pivoted to the total lever 59 at 98 (Fig. 4) is a link 98 extending rearwardly and provided with a slot 98 engaging over a stud 9| on the left-hand arm 84. This slot is of such length that it does not interfere with the forward movement of the arms 84 when the latter are moved by the amount keys at which time, of course, the total lever 59 remains stationary. When the total lever is pulled forward to take a total, the link 98, acting on'the stud 9|, pulls the arms 84 forward, thereby moving the bail 83 forward and rocking the arm 19 in the same manner as when an amount key is depressed. When the total lever is restored rearward by the operator, which action may be assisted by a spring described later, the arm I9 and associated bellcranks I4 and the paper rolls are restored to normal. Thus, the paper is shifted from visible to printing position and returned during the total-taking operation as well as during depression of the amount keys.

The paper equipment can be rocked as a unit to an accessible position and it can also be detached as a unit from the machine. For this purpose the parts are mounted in two side plates GI (Figs. 1 and 4) whose lower ends 82 are notched to go over a shaft 63 carried by the frame plates of the machine. These plates and the paper equipment, including the storage and supply rolls, can be rocked counterclockwise by means of the handle 8| (Figs. 1 and 4) to bring the paper equipment to a more accessible position. Also, the unit can be removed by lifting if oil the shaft 88.

The various novel features of the paper section are not claimed herein, the same being the subject matter of my copending application Serial No. 147,430, flied June 10, 1937, in which this paper equipment is also explained in more detail.

2. Indexing the type-carrying elements The type used for printing items and totals are carried by type-carrying members in the form of type wheels 68, best shown in Fig. 19. These type wheels are rotatably mounted on a shaft 88 and are differentially positioned underv the control of the amount keys in item entering and under the control of the register pinions in total taking. A novel construction and arrangement has been provided for promoting easy key depression, the nature of which will appear as the description proceeds, but attention is' called at this point to the fact that the three lower orders of type wheels are used for printing items while all of the type wheels are used for printing totals and that, normally, as shown in Figs. 8 and 18. the item-printing wheels have their 0's at the printing line while pinions in the higher orders, of which there are four, have blank spaces at the printing line. For convenience in description, the three lower order type wheels will be called the item type wheels while the four higher orders will be called the extra type wheels. The indexing of the item type wheels will be explained first.

The item" type wheels are indexed under the control of the three denominational bails 38 that are differentially positioned by the various amount keys of each denomination. Referring to Fig. 7, it will be recalled that the denominational bails 38 are carried by arms 3i pivoted on the shaft 32. Each of these yokes has a forwardly extending arm II9 having a toothed sector I28 on its end. Each toothed sector meshes with a toothed sector I2I pivoted on a shaft I22 with the result that, when an amount key is depressed in any denomination, the corresponding sector I2I will be differentially positioned in accordance with the value of the key. Each sector I2I meshes with a gear I23 (Fig. 7) and these gears are mounted on individual shafts I24, as best shown in Figs. 2 and 9. These shafts extend to the right, viewing the machine from the front and as viewed in Fig. 8. Mounted toward the right-hand end of each shaft is a gear I28, said gears being numbered No. 1. No. 2 and No. 3 in Fig. 2. The gears I28 engage, respectively, gears I21, the engagement being with the three right-hand ones, as shown in Fig. 8, or the three left-hand ones in Fig. 9 except that, in Fig. 9, the extreme left-hand gear is for a special char acter printing, later explained. Each gear I21 is connected by a link I28 (Fig. 8) to a sector I28 pivoted on a shaft I38. Each of the sectors I29 meshes with a type wheel 88 and constitutes an operating sector for said wheel.

From the above it will be clear that, when an amount key is depressed, the ball 88 in its denomination is moved difl'erentially which rocks the arm H9 and the sector I28 to a corresponding position. This rocks the sector I2I, rotates gear I23, shaft I24, gear I28 and gear I21 to move the link I and rock the sector I2! to rotate the type wheel I for the denomination in which the key has been depressed to a. position corresponding to the value of the key. Fig. 2 shows a sector I29 in normal position and Fig. 7 shows it in a moved position. Thus, the item" type wheels in the three lower orders are differentially positioned through positive connections with the amount keys.

An extra type wheel for printing special characters, not illustrated in Fig. 8, is indexed in a similar manner to the several orders of the foregoing mechanism by means of gears I2I, I23, iii and l2l, illustrated in Fig. 9. This mechhas been omitted from most of the figures in order not to confuse the drawings. It will be understood that this order of mechanism is under the control of the character section of the machine which includes the usual Cash, No sale and Paid out indications, the latter two being controlled by the No sale and Paid out" keys.

When a total is to be taken, the type wheels be differentially positioned under the control oi the register and this applies not only to the item type wheels, but also to the extra time wheels that normally have blank spaces at the printing line. In order that the item type wheels may be positioned under the control of register, it is necessary that the connections with item keys be disabled and this portion of the mechanism will be described first.

Referring to Fig. 8, the total-taking lever 59 is pivoted on the shaft 60. Fixed .to this lever and rotatable on said shaft BI! is a collar I3I to which is fixed an arm I32 (Fig. carrying a stud 933 operating in a cam slot I34 of a member 35 slidably mounted on the shaft 60. The member 235 is fixed by means of a shaft I35, collars I36, and nuts I36 to three rearwardly projecting arms I31 also slidably mounted on the shaft 8B. The shape of the cam slot I34 is such (Fig. 10) that, when the total lever 59 is pulled forward, the member I35, together with arms I31, will be slid to the right in Figs. 8 and 10 at the beginning of the movement of said total lever. The rear ends of the arms I31 are positioned in slots in the hubs of the three sectors I2I (Fig. 10). Said sectors I2I, in addition to being rotatable on shaft I22, are also slidable on said shaft. When the arms I31 are moved to the right (Fig. 10) by the forward pull on total-taking lever 59, the sectors I2I are also moved to the right to the dot-dash position shown in Fig. 10 and said sectors are thus disengaged from the sectors I20. Thus, the connection between the amount keys and the type wheels in the three lower orders is disabled.

Before describing how all the type wheels are indexed under the control of the register, the operating connections for the extra" type wheels will be explained. Each extra type wheel has an operating sector I29 (Fig. 8) pivoted on the shaft I and connected by a link I28 to its gear I2I. Each gear I21 meshes with a gear I26 (Figs. 8 and 9), said gears being numbered No. 4, No. 5, No. 6 and No. 7 in Fig. 2. The gears are carried by individual shafts I24- (Fig. 9) and the lefthand ends of these shafts carry gears I23- (Figs. 8 and 9) that mesh with sectors I2I" (Fig. 8) pivoted on the shaft I22 which, it will be recalled, is the shaft that carries the sectors I2I for the three lower orders. Thus, the sectors I2I' are operatively connected to their individual type wheels.

In order that the type wheels may be differentially positioned under the control of the register, mechanism illustrated in Fig. 6 is provided. Each register pinion I. has a snail cm I" associated with it, as described in more detail In Horton 1,326,504, whose edge is contacted by stud Ill on a lever H2 pivoted on .the shaft I" and urged counterclockwise, as viewed in Fig. 6. by a spring I84. The forward lower end of each arm IE2 is connected by a link I with a yoke member I61 having an upwardly projecting arm IiI provided with notches I68 corresponding to the digital values of the positions of the register pinion. The yoke IiI is urged clockwise, as viewed in Fig. 6 by a spring I. The parts are arranged so that each notched arm IGI continuously reflects the position of its register pinion and thus forms a differential stop, which stops may be employed to arrest the type wheels in positions corresponding to the amount in the register.

For differentially positioning the type wheels, the arms IBI are engaged by studs I38 as shown in Figs. 11 and 13. There are two sets of these studs I33 and I38, as shown in Fig. 10, the righthand set of three in Fig. 10 comprising the studs I38 for the three lower orders or item" type wheels and the left-hand set comprising studs I38 for the four extra type wheels. The studs II! are carried by the sectors IZI" but the studs I38 are carried by arms I40 (Figs. 6, 8, 11 and 12) pivoted on the shaft I22. The studs I38 with their arms I40 and the studs I38 with their sectors I2I are urged counterclockwise (Figs. 6 and 12) by individual springs I (Fig. 10). which is in a direction to cause the studs I28 and I38- to move into engagement with the notches in the arms I61. Normally, however, the studs I38 and I3! are prevented from moving into engagement with arms I61 by arms I42 fixed to the shaft I22 (Figs. 6, 10 and 11).

Referring to Figs. 11 and 13, there is fixed to the shaft I22 an arm I54 carrying a stud I53 operating in a slot I52 in the forwardly pro- Jecting arm IBI of a cam member I49 pivoted on the shaft I50 (Fig. 13). The member I40 has a cam slot I4! in which is positioned a stud I41 on the total lever 59 (Fig. 8). The arrangement is such that, when the total lever is pulled forward, the member I4! is rocked counterclockwise (Flg. 11) and the member I48, acting through the arm III, stud I52 and arm I54, rocks the shaft I22 counterclockwise, thereby moving the arms I42 counterclockwise away from the studs I3! and III. This frees said studs so that they can be moved counterclockwise by their springs I4I until the studs engage notches in the respective arms I41. Thus, when the total lever I9 is pulled forward, the arms I40 with the studs Ill and the sectors I2I with their studs III are differentially positioned in accordance with the positions of the arms I61 controlled by the register pinions. When the total lever is moved rearward, the arms I42 act as restoring arms to pick up the studs I38 and I"- to restore the parts to normal.

In order that the type wheels Il may be positioned, the studs I I! must be connected to the item type wheels and provision is made for causing this to occur automatically when the total lever is pulled forward.

As previously explained, the "item type wheels normally have their 0'5" at the printing line while the extra" type wheels have blank spaces at said printing line, their "O's being one step removed from the printing line. All the type I wheels must be coordinated in total taking, or,

to put it another way, the item" and the extra type wheels must be put in step.

Referring to Fig. 10, it will be observed that the studs I38 project from both sides .01 the arms I40. The portions of these studs projecting to the left in Fig. are positioned to engage openings I39 (Fig. 12) in the sectors I2I when said sectors are slid laterally by the movement of the total-taking lever 59. Normally, however, the studs I38 for the sectors I2I for the "item type wheels are not in line with the openings I39 but are one step removed therefrom, as shown in Fig. 12. As the total lever 59 is moved forward, the arms I42 that normally hold the studs I and I38 against movement are rocked to release said studs for counterclockwise movement (Fig. 12) under the urge oi the springs I4 I. Since the studs I39 are directly connected to the sectors IZI said sectors will be moved immediately and, through their connections with the extra type wheels, will move said type wheels immediately. However, the sectors III and their connections to the "item type wheels will .not be moved immediately because the arms I40 carrying studs I38 must move one'step before the studs I38 will be in alignment with the openings I39 in the sectors IZI. But, after the studs I38 have moved one step, the sectors I2I will be slid laterally to connect themselves to said studs, after which said sectors move with said studs to differential positions governed by the registercontrolled arms I61'= in the three lower orders. The effect is that the two sets of type wheels are coordinated, or, to put it another way, the extra type wheels are moved a step to put them in step with the "item type wheels before the entire group is moved to total-taking position.

The timing of the parts is obtained by the irregular shaping of the cam slot I48 in the cam member I49 (Fig. 11). This slot has an initial inclined portion which, during the initial movement of the total-taking lever 59, causes the arms I42 to be moved to free the studs I38 and I38"- for movement. During this movement, the studs I38 move a step to move the extra type wheels a step and the studs I38 move into line with the openings I39 in the sectors I 2|. The cam slot I48 then has a dwell portion and, while this dwell is operative, no further movement of the arms I42 occurs and the studs I38 and I38 are held in their one-step position. During this time the movement of the total lever 59 causes the sectors I 2| to be shifted laterally by means of the parts I 3| to I31, inclusive. Following the dwell portion, the cam slot I48 has another inclined portion which causes further movement -of arms I42 andfrees the entire set of studs I38 and I38 with the parts connected to them for movement to differential positions determined by the arms I61 controlled by the register pinions. In this manner all the type wheels are positioned under the control of the register.

When the total lever 59 is released, it is restored rearward by the spring I acting on the cam member I56, having a cam slot I51 in which the stud I41. on the total lever 59 engages, although, ordinarily, the operator pushes the lever rearward after pulling it forward. As the said lever 59 moves rearward the arms I42 are rocked clockwise and they pick up the studs I38 and I38 to restore the parts to normal. As the parts are restored to normal position, the sectors I2I are slid laterally so as to be disengaged from the studs I38 and reengaged with the sectors I20. Thus, at the end of a total-taking operation, the parts are restored to normal and the machine is again in condition for item-entering operatlons.

A full stroke of the total-taking lever is insured by providing it with a full-stroke sector I45, shown in Figs. 11 and 13, with which cooperates a full-stroke pawl I46 operating in the usual manner.

Provision is made for aligning all the type wheels without placing any appreciable load on the keys. Referring to Figs. 4 and 5, it will be recalled that the bail 83 is moved forward by movement of the total lever 59 to total-taking position. As this bail moves forward, it engages a slot I15 (Fig. 5) is a lever I18 pivoted at ill. The forward end of this lever is provided with a toothed sector I 18 engaging a gear I19 fixed on an aligning shaft or bail I80. The shaft I83 extends across the group of operating sectors I29 (Fig. 7) adjacent their toothed faces. This shaft is semicircular in cross section and positioned so that, when the shaft is rotated from the position of Fig. 5 to that of Fig. 7, the rounded portion of the shaft will engage between the teeth oi the operating sectors I29 to accurately align them and their type wheels in position. The force necessary to rock the lever I16 and rotate the shaft I is very small and places no appreciable load on the keys.

3. Printing hammer operation the type wheels, enables the machine to be oper- Cir ated with an exceedingly light key depression.

Referring to Figs. 4, 19 and 21, the printing hammer 69 is in the form of a bail pivoted on the shaft I05 and urged counterclockwise by a spring I08, connected at one end to a stud on the hammer bail and at the other to a stud on one of the side plates of the paper section, the

' hammer and its spring being carried by said paper section and being removable with it. The hammer 69 supports a platen 240 that extends laterally across all the type wheels so that, when the hammer is fired, the platen will be able to make an imprint from each of the seven type wheels. The line on which the platen strikes is called the printing line.

The hammer is cooked by forward movement of the bail 83 (Fig. 4), which bail, it will be recalled, is moved forward by depression of the amount keys as well as by movement of the total lever 59. Pivoted on the bail 83 is an arm III) urged clockwise (Figs. 4 and 21) by a spring IH'I into engagement with a stud.24I on a portion of one of the side plates SI of the paper section. The forward end of the lever IIO has an abutment face 242 (Fig. 21) positioned to engage a square stud III on a downwardly projecting arm 243 of the printing hammer ball. The normal position of the parts is shown in Fig. 4. As the'bail 83 approaches the end of its forward movement, the arm I I0 is cammed counterclockwise by the stud 24I (Fig. 21) which engages in a cam slot formed 'by the edge of said arm and a projection 244 on it. This movesthe abutment end 242 away from the stud III and suddenly frees the printing hammer which is thereupon fired to printing position with a percussive action by its spring I06.

The normal position of the hammer is the dot-.

the type wheels no matter what the total may be. If the total is less than the seven-wheel capacity of the type wheels, "0's" will be printed to the left, which distinguishes the item as a total. Obviously, if the impression from all the type wheels is to be as clear as that from the three item type wheels, the hammer must be driven to printing position with greater force in totaling than in item-printing operations. If, however, the hammer is cocked by the ball 02 and fired with only sufficient force to make a clear impression from three type wheels, it will not make as clear an impression from seven type wheels and the print will not be the same character; that is, it will be lighter than the item print. Clear and uniform impressions are desired. Accordingly, provision is made for firing the hammer with a greater degree of force when all the type wheels are indexed in total taking and when an imprint is desired from all of them.

When the total lever 00 is rocked forward, the ball 00 is moved forward as in item-entering operations and the arm IIO acts to cock the printing hammer as previously explained. But the printing hammer spring is given an additional tension in total taking as follows:

Referring to Fig. 4, the total lever is provided with a projection H8 that is integral with it and that moves forward as said lever moves forward. Positioned in the path of this projection, as shown in Fig. 4 but best in Figs. 21 and 22, is one arm 200 of a three-armed member 2M, shown best in Figs. 19 and 20, where it is viewed from the side opposite to that shown in the other figures. This three-armed member is pivoted on the shaft I" and urged to a normal position by a centering spring 25h (Fig. 21). The threearmed member "I has an upwardly extending arm 252 positioned to engage a stud 254 on the printing hammer bail 0!.

As the total-taking lever is moved from the dot-dash to the full-line position of Fig. 20, and as it approaches the end of its movement to total-taking position, the projection I I3 engages the arm 200 of the threearmed member 25I and rocks it counterclockwise in Figs. 19 and 20 which is clockwise in Fig. 4. The arm 253, engaging the stud 250, thereupon rocks the printing hammer ball 0! counterclockwise beyond the pomtion to which it is moved by bail 83 and arm III to stretch the spring I00 a greater distance than in item-entering operations. The distance that the hammer is moved in this total-taking operation is shown by dot-dash position in Fig. 22 marked Totaling. In other words, when the total lever is moved to total-taking position, the printing hammer is not only cocked as usual but the spring is given a greater tension by additional mechanism operated by said totaltaking lever. There is ample force available for giving the spring this extra tension because the total-taking lever is a long one with ample leverage, and it is the only member the operator has to move in the total-taking operation.

When the printing hammer is fired in both item-entering and totaling operations, it is moved past its normal to a "printing" position as illustrated in Fig. 22. Printing occurs with a sharp percussive action after which the printing hammer is returned to normal by its spring I00. It is then in a position to permit shifting of the paper P from visible to printing position and return. Provision is made for preventing rebound of the hammer by providing a stud 2" (Figs. 4, 21 and 22) for snubbing the spring ill, but this rebound feature has not been claimed in the present case,.the same being the subject matter of copending application Serial No. 147,431, filed June 10, 1937, where it is disclosed and described in more detail.

Impressions on the paper P are made by means of an ink ribbon R (Figs. 4 and 21) which extends over the printing line of the type wheels and between said wheels and the paper strip. This ink ribbon is carried by two spools mounted on shafts 00 and 91 carried by detachable frame that hooks over a shaft 05 and rests on the shaft 00. The ink ribbon unit may be detached as a unit after the paper section has been detached. This facilitates replacement of ribbons.

The ink ribbon is moved step by step by means of pawls I00 and IN carried by a three-armed member I02 pivoted on a shaft I02 (Fig. 4). These pawls are positioned for alternate engagement with ratchet wheels 00 and 00 fixed to the shafts on which the ribbon spools are mounted. The three-armed member I02 has a downwardly projecting arm I02 provided with two notches for engagement over a stud I02 on an arm or slide I02 carried by an arm I02 pivoted on shaft I02, said slide being urged upward by a spring I02 The slide [02, together with its arm I02=, is rocked clockwise in Fig. 4 and returned counterclockwise by each movement of the universal bail II acting through an arm I03 having a stud I00 engaging a cam slot I03 in the lever I02. In a position of the parts shown in Fig. 4, the pawl I00 is active to operate the ratchet wheel 38. This will occur in each operation of the machine by the amount keys. When the ribbon has been exhausted from the spool 01 to which it is attached, said ribbon will I resist movement of the ratchet wheel 90 by pawl I00 and this resistance will cause the arm I02 to move relative to member I02, and the stud I02 will move to the left-hand notch in arm I02 The parts are then positioned so that the stud IOI will be active on the ratchet wheel 00 to move it to wind the ribbon in the opposite direction.

1mm v. TOTAL Panvrmo In item printing, the operator merely depresses the proper amount keys and releases them, the operation resulting in entering the item in the register and printing it. During this operation, only the item type wheels are indexed. No force is required to index the "extra type wheels or to move them out of printing position. Also, during this operation, the hammer is cocked only sufficiently to obtain a clear impression from the three lower order wheels. This reduces the force required for item printing to a very minimum. It will be appreciated that by far the greatest majority of operations on a cash register of this type are item-entering operations and, consequently, as far as the normal and usual operation of the machine is concerned, the force required for key depression is a minimum because only those parts are conditioned that are necessary for item-entering and printing. No printing occurs in any but the three lower orders as indicated in the sample of work in Fig. 3.

For total printing, the operator grasps the long total lever 89 and pulls it forward. The leverage is large and consequently additional parts may be easily operated. During this total-taking operation, all the type wheels are indexed under the control of the register and the printing hammer is fired with a greater degree of force so as to obtain a clear println impression from all the type wheels, which im ression will be of the same character as to its being light or heavy as that obtained from the item wheels.

This control of both the indexing of the type wheels and of the force of printing impression is a very important advantage of the construction because it enables the machine to be operated with a minimum of force during a major portion of its use and then provides that it may be operated with a greater degree of force, but quite easily, when an extraordinary operation such as total taking is required.

In total taking, the register is cleared and the clearing mechanism directly associated with the register is of the type shown in Horton Patents No. 1, 326,504 and 1,415,174, to which reference is made for detail. The mechanism for operating the clearing mechanism will, however, be described.

The clearing operation requires that the pawls 53 (Fig. 6) be released to enable the springs "54' of the levers I82 to rock the levers clockwise to' normal and restore the register pinions to normal as described in said Horton patents. For this purpose, the total lever 59 is provided with a stud I81 (Fig. 18) for engagement under certain conditions with the rear hooked end I88 of a two-armed lever I89 pivoted at I90 to a lever I!" and urged clockwise (Fig. 18) by a spring I90. The lever I90 is pivoted at I92 to a stationary shaft and it has a forked connection I93 with a stud I94 carried by one arm of a bell crank I95 pivoted at I98. The other arm I91 of this bell crank carries a stud I98 positioned to enga e the cam edge of cam lever I99 pivoted at I99 The lever I99 has a forked connection 200 with a stud 20I on an arm 202 fixed to a clearing shaft 202 corresponding to the shaft I of the Rinsche Patent 1,802,927 and having a series of fin ers 203 that are positioned to enga e the pawls 53 to disengage the latter from the studs 54. Members corresponding to the members z of the Rinsche Patent 1,802,927, which normally prevent backward rotation of the register wheels during item entering operations, are also operated, as disclosed in said Rinsche patent; by parts actuated by the shaft 202 to free the register wheels for reverse rotation in clearing operations.

Normally, the two-armed lever I89 is held in the position of Fig. 18 by a lever 206 pivoted at 201, the lever end of said lever engaging a stud 205 in the lever I89. The parts are held in this position by a lock that later will be described. In this position of the parts, the end I88 of lever I89 is above the path of the stud I81 and the clearing mechanism will not be operated when the total lever is moved.

When the total lever 591s ulled forward. the stud I81 passes the lever I89 and said hooked end I88 of said lever I89 drops over the stud. As the total lever is returned. and near the end of the return movement, the stud I81 engages the hooked end I88 and pulls the lever I88 rear ward. This rocks the lever I9I clockwise and it, in turn, acting through the crank I95-I 91 and cam arm I 99, rocks the clearing bail 202 clockwise to move the fingers 208 into engagement with the pawls 58 to disengage the latter from the studs 54. This occurs at the very last part of the return movement of the total lever and, when it occurs, the register pinions are caused to return to zero by the clearing mechanism.

Provision is made for taking a subtotal which consists in taking a total in the usual manner without clearing the register. This is accomplished by retaining the two-armed lever I89 in its normal or ineffective position. It will be apparent that, when the member 206 is in the fullline position of Fig. 18, it will hold the hooked end I88 of member I89 upward in the full-line position of said figure where it is out of the path of the stud I81. When in this position, the movement of the total lever will not operate the clearing mechanism and, hence, the total will be taken and printed but allowed to remain in the register.

KEY LOCK Contract.

It is often happens that the operator desires to know what total is in the register. However, the proprietor does not want the operator to be able to clear the register. To enable each to exercise the proper control of the machine, a key lock is provided which, when operated by the operator's key, permits only a subtotal to be taken, but, when operated by the proprietors key, enables either a subtotal or a total to be taken.

The total lever 59 normally lies beneath the top.

plate 208 of the machine (Fig. 1) which plate is normally concealed by the hinge cover 209 controlled by a key lock 2I0. When the cover 209 is closed, the operator can observe the entries on the paper through the sight opening 209*, but, otherwise, the interior of the machine is inaccessible and nonvisible. By raising the cover, the operator can observe the amount standing on the item counters M I, he may read the register dials 86 and he gains access to the printing section. The key lock 2I0 for the cover 209 is one lock which can be opened by both the operators and the proprietors keys.

The total lever is normally. concealed by a shutter 2I3 (Figs. 1 and 17) which is under the control of a key lock 2 (Fig. 1) that may be operated by either the operator's key 2| 5 (Fig. 15) or the proprietors key 2I6. As stated, both these keys also fit the lock 2I0 so that both the operator and the proprietor can unlock the lid .209. Both the operator's and the proprietors keys will operate the locks 2 to move the shutter 2| 3 and both of them release the total lever 59 for its full operation by either the proprietor or the operator, but the same type of operation of this lever by the operator will result in taking only a subtotal, whereas its operation by the proprietor may result in taking either a total or a subtotal at the proprietors option.

The key lock 2I4 (Figs. 14-17) is of the tumbler type and the left-hand tumbler 2" is normally oil center as shown in Figs. 15 and 16, being urged to this position by a spring shown in Fig.

When the operators key 2I5 (Fig. 15) is inserted, the tumbler 2I'I is not centered, which means that the cylinder 2I8 can be moved only in one direction, that is, counterclockwise in Fig. 16. However, if the proprietors key 2I8 is inserted, a rise on it will center the tumbler 2!! allowing the cylinder to be turned in either direction. Rotation of the lock cylinder controls mechanism as follows:

When the cylinder is rotated by the operator, he can rotate it counterclockwise only in Fig. 14. As it moves, a stud 220 on an arm 2!! fixed to the cylinder moves with it. The stud 220 first engages the cam edge of a lever 22i pivoted at 222 and urged clockwise by a spring 226. The lever 222 has another arm 223 that, normally, is positioned in front of a stud 224 on the shutter 2l3. The first action is, therefore, to unlock the shutter 2".

As the cylinder is rotated farther counterclockwise beyond the position for unlocking the shutter 2i3, the stud 220 engages the end of a slide 225 and moves it to the left, said slide being urged to the right in Fig. 14 by the spring 226. The right-hand end of slide 225 has a hook connection 221. with the shutter 2l3 which is pivoted at 228 to the plate 208 as shown in Fig. 14. The movement of the slide 225 to the left rocks the shutter counterclockwise in Fig, 14 to move said shutter to open position.

Thus, when the operator inserts his key and turns the lock to the left or counterclockwise, the first action is to unlock the shutter M3 and the next action is to move the shutter so as to make the total lever 53 accessible.

When the operator moves the total-taking lever, all that he will obtain is a subtotal. The arm 2 i 9 on the lock cylinder has a bent extension 23!) (Figs. 14 and 17) whose elbow is normally in front of a stud 23i (Fig. 14) on an arm 232 forming a portion of a slide 233 having studs 234 mounted in slots in the slide 225. The slide 233 has a forked connection 235 with one arm of a bell crank 236 pivoted at 231, the other arm of this bell crank having a forked end 238 that is astride the lever 288 that controls the position of the member I85 (Fig. 18). The slide 233, normally, is prevented from moving to the left in Fig. 14 by the extension 238 which is in front of the stud 23i, but the slide 225 can move to the left to unlock and move the shutter 2 i3 by reason of the stud and slot connection 234 between the two slides. The result is that, normally, the bell crank 236 cannot be rocked clockwise from its Fig. 14 position in which position it holds the lever 205 in the Fig. 18 position with the member I89 ineffective. The turning of the lock cylinder 218 counterclockwise in Fig. 14 does not release the slide 233 because the cam edge of the extension 23!! passes in front of stud 23 I. Consequently, when the key lock is turned counterclockwise by the operators key, the lever 205 cannot be moved and all that the operator can obtain by moving the total lever is a subtotal.

However, when the proprietors key 2 I G is used, -the lock cylinder 2!! can be moved in either direction. If the proprietor merely wishes to take a subtotal in the same manner as the operator, he can do so by turning the lock to the left or counterclockwise. On the other hand, if he wants a total that will clear the register, he turns the lock clockwise or to the right. When the lock is turned 'to the right the stud 220 first acts on the lever 22 i-223 and unlocks the shutter 2l3. Further movement of the key causes the end of the bent arm 233 to engage one of the studs 234 (Fig. 17) carried by the slide 233 to move said slide to the left in Fig. 14 or to the right in Fig. 17. The stud 234 on the slide 233 engages the end of the slot in the slide 225 and moves the latter to the left in Fig. 14 to open the shutter. Also, as the slide 288 is moved to the left in Fig. 14 or to the right in Fig. 1'7, the bell crank 238 is rocked clockwise in Fig. 14, or counterclockwise in Fig. 17. which moves the lever 208 in Fig. 18, thereby lowering the member I" so that its hooked end I" will be in the path or the stud I" on the total lever. Subsequently, when the total lever is moved, a total will be taken and the register cleared in a manner heretofore explained.

From the above it will be clear that both the proprietor and the operator can open the shutter to obtain access to the total lever and, in each case, the total lever is free to be moved its full distance. Normally, this total lever will cause a subtotal to be taken; that is, the total will be printed without clearing the register and, as far as the operator's key is concerned, this condition is not changed. However, if the proprietor inserts his key and turns the lock to the right instead of to the left, a mechanism is set so that, when the total lever is moved, the total will be printed and the register cleared.
